摘    要:
自制了一种新型固体酸催化剂SO2-4 MoO3 TiO2。红外光谱分析表明,其表面具有强酸中心。由其吸附吡啶的红外光谱表明,这种新型固体酸催化剂的表面主要存在B酸点。该催化剂对合成联苯乙酸乙酯的反应催化活性高,联苯乙酸转化率可达92%,而且回收容易,重复使用性能好。考察了反应条件的影响,获得了该反应的优化条件。

关 键 词:固体酸  催化合成  联苯乙酸乙酯

Abstract:
A new SO~(2-)_4-MoO_3-TiO_2 solid acid catalyst was prepared. IR results indicated that there existed strong acid centers on the surface of the catalyst. IR results for pyridine absorption on the surface showed that there mainly existed Br?nsted acid sites. The catalyst exhibited high activity for synthesis of ethyl 4-biphenylacetate, with felbinac conversion of over 92%. The catalyst can be easily recovered and has good performance for repeated use. Optimum reaction conditions for the esterification were obtained.
Keywords:SO~(2-)_4-MoO_3-TiO_2 solid acid catalyst  synthesis of ethyl 4-biphenylacetate
